How many miles/Km's on your bike? im at 24000km's may do mine next year? also what did you put in oem NGK's?

its at low 16000ish. I just wanted to change them for a piece of mind, and since i laid my bike down in the canyons the other day it was "acting funny". (loss of throttle power at random RPM ranges, choking of the engine coming from idle, etc) Changing the spark plugs fixed the issue.

look at that website it looks like my plugs were "too hot", so lean mixture.

Those Iridium are a blow to the wallet, but they're definitely well worth the investment. I was wondering, did you by any chance lube the threads with dielectric grease? I had just recently changed mines, but I'll most likely be pulling them out again just to lube up the threads.

Yes they are a blow to the wallet but it wasn't too bad, i mean they are good for 16000-32000 miles.....so in the long run its not too bad. Thats the way i see it. New plugs are sexy, i feel the difference.

o? no i did not put the grease.. What are the benefits of greasing it with dielectric grease? They were a hassle to do, well at least 2-3rd spark plugs were. Tiny space.

but if it is a worthful investment to put on the grease i may just take it apart and put them on.

you don't but dielectric grease on the threads. That goes in the boot of the plug wire. It makes it easier to remove the boots when the time comes so you don't rip the wire out of the boot. On the threads of the spark plug you put Anti-Seize. Neither of these are required, but they just make it easier to remove the plugs/wires in the future.

Yup, sorry for the misleading information. I figured out that the dielectric grease is for the boot and the anti-seize is for the threads a little later after reading a bit more on some other forums.

However, Bridge_Jumper, would it really matter if you put anti-seize and dielectric on or would it not be as necessary as I thought it would be?

its not required. Most people only put them on because it makes it easier to remove them the next time around. For instance: I just changed the plugs and wires on my 07 Grand Prix a few weeks ago. They are iridium plugs and GM says they are good for 100k miles. I did my 100k service so I changed plugs, wires, oil, filter, transmission filter, and drained/replaced trans fluid.

Now since these were original plugs and wires, if there was dielectric grease or anti-seize applied at the factory, there was none left(I doubt there was any originally applied). I kept telling myself there was no way that I was going to be able to do this without busting my knuckles open..... Well I did, about 5 times. Thats how stuck they were. Fast forward to today, If I were to go out to my car and pull plugs, it would be easy as pie because I applied the dielectric grease and anti-sieze.

Overall, Not required, but if you ever plan on messing with your plugs in the future, apply it. They are only a few bucks for a little 1 time use packet at an auto parts store. Spending 2 bucks to make it easier down the road is well worth saving your knuckles

The plugs look perfect. Definitely at the end of their life, but they look exactly as you would want them to.

As for dielectric grease and anti-seize, be careful which dielectric grease you use, some of them won't withstand the high voltages involved with the ignition system, but provided a decent one is used you can't go too far wrong. Anti-seize is also a good idea, but don't get it anywhere near the electrode or bridge. You don't want it shorting out your spark, you only want a little on the threads.
